The inner layer comprises a first porous arrangement of fibers defining a first tube comprising an inner wall and an outer wall. The outer layer comprises a second porous arrangement of fibers defining a second tube comprising an inner wall and an outer wall. The second tube surrounds the first tube. A plurality of macropores extend through at least the inner and outer wall of the first tube. The inner and/or the outer layer can comprise a biofragmentable material configured to mechanically fracture into one or more fragments over time. Methods of creating graft devices are also disclosed.
